The present invention relates to improvements in sanding devices andmore particularly to one designed for use in connection with motorvehicles.

The primary object of the invention is to provide a device of thischaracter adapted to be placed upon a motor vehicle, the constructionbeing such that sand or other material is discharged in advance of therear wheels of the vehicle to prevent skidding or to obtain tractionwhen stalled or on slippery roads or streets.

Another object of the invention is to provide a device of this characterso constructed that it can be quickly placed in operation by the driverof the car.

Another object of the invention is to provide a device of this characterso constructed that upon swinging an actuating lever the contents of thehopper will be discharged into chutes and from thence to points inadvance of the rear wheels of the vehicle.

With these and other objects in View, this invention resides in thenovel features of con struction, formation, combination and arrangementof parts to be hereinafter more fully described, claimed, andillustrated in the accompanying drawings, in which:

Figure 1 is a view of a motor vehicle, showing the position of thedevice with respect thereto.

Figure 2 is a sectional view on the line 22 of Figure 3.

Figure 3 is a fragmentary bottom plan view.

Figure 4 is a transverse sectional view.

Referring to the drawings, 1 designates a hopper which is mounted underthe front seat 2 of the vehicle or in any other convenient location. Thefloor board 3 of the vehicle provides a bottom for the hopper and hasformed therein a pair of discharge openings 4.

Chutes 5 are secured to the under surface of the board 3 and haveopenings 5 formed in their front sides, said chutes being disposeddirectly under the openings 4 so that the sand passing through saidopenings will gravitate into the chute. Each chute has connected theretoa hose 6which has its discharge end located in advance of a rear wheelso that the material discharged will be distributed prop erly foreffective operation. It will, of course, be understood that steel tubingmay be used in lieu of the hose, if found more desirable. f 7

Fixed to, the under surface of the board 3 are blocks 7 which havesecured thereto metal plates 8, and pivotally connected to said metalplates are metal plates 9,the latter plates having blocks 10 carriedthereby. The plates 8 and 9 have associated therewith the terminals ofcoil springs. 11 which are arranged to'surround the pivotal rods 12 ofthe plates. By providing the springs the same act to hold the blocksnormally flush against the under surface of the floor board 3 soas toclose the openings 4, thus preventing leakage of sand from the hopper 1.The forward ends of the plates 9 areprovided with arms 13and to whichare connected the rear ends of the cables 14, said cables being disposedin diverging relation and having their forward ends secured to aturnbuckle 15, said turnbuckle being pivoted to the crank 16 formed uponthe lower end of the shaft 17. I The shaft 17 is journaled in the floorboard and extends upwardly and adjacent the front wall of the seat 2.The upper end of the shaft 17 is provided with a handle .18 tofacilitate rotation of the shaft so that the crank arm will be shiftedto pull upon the cables 14, which action will swing the blocks 10downwardly so that the contents of the hopper will discharge into thechutes. The shaft 17 is journaled in a suitable bracket 19.

Fixed upon thefioor board 3 adjacent the crank 16 is a stop 20 which isadapted to limit the swinging movement of the crank 16 when the same isswung to open the openings 4, said stop holding the shaft- 17 in aposition slightly past dead center- In this manner, the blocks can beheld in their open position until the rotation of the shaft is reversed,and after which the springs 11 will cause the blocks 10 to move toposition to close the openings 4. These blocks have mounted thereon pins21 which serve to prevent clogging of the openings 4.

Mounted in the hopper and located between the openings 4, is a deflector22 which will obviously serve to direct the contents of the hoppertoward said openings.

From the foregoing, it is thought that the construction, operation, andmany at vantages of the herein described invention will be apparenttothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction,

may be resorted to without departing from" the spirit or sacrificing anyof the advantages of the invention.

What is claimed is: i

1. A sanding device for motor vehicles comprising ah'opper mounted uponthe floor of the vehicle, chutes fixed to the floor below the hopper,said'fioo'r having-openin s therein for discharging sand from the hopperinto the chutes, blocks-'pivotally' connected with the floor fornormally closing the openings, a shaft supp'orted by the vehicle,andmeans connecting the shaftand'blocks for swinging the blocks open topermit passage of sand through the openings into the chutes, and meansfor discharging sand from the chutes.

2. A sanding device for motor vehicles comprising a hopper,chutes fixedto the floor of the vehicle below the hopper, said floor having openingsthereinafiording communication between the hopper and chutes, blockspivotally connected" with the floor for nornially closing the openings,a shaft carried by the vehicle, a turnbuckle connected to theshaft,cables connecting the turnbuckle and blocks, said blocksbeingswingable to permit sand to pass through the openings into thechutes upon actuation ofthe shaft.

3. A sanding device for motor vehicles comprising a hopper, chutes fixedto the floor of the vehicle, said floor having openings therein, blockspivotally connected with the floor, means for'yieldably'holding theblocks in position to close the openings,a shaft r'otat'ably supportedby the vehicle and having a" crank upon its lower end, a turnbuckleconnected tothe'crank, and cables connecting the turnbuckle'andblocks'to swing the blocks open upon actuation of the crank.

A sanding device for motor vehicles comprising a hopper mounted upon thefloor of the vehicle, chutes' fixed to the floor, said floor havingopenings therein aiiording communication between the hopper and chutes,blocksnorinally closing the openings,-plates fined to'the blocks, saidplates'beingpivotally and-yieldahly' connected with the floor,- saidplates liaving arms, a ate rotatably moiintec upon the vehicle, a crankcarriedhy the shaft, and means connecting the crank and arms forswinging the blo'ck's'open upon actuation of the crank; V p
